Abstract

The invention discloses a manufacturing method of a superconducting magnet for a high-temperature superconducting maglev train. The manufacturing method comprises the steps of A. coating the surface of a high-temperature superconducting strip (1) with a curing agent; winding the high-temperature superconducting strip (1) from inside to outside during coating to form a hollow circular ring shape or solid round cake, and enabling the inner end (1a) of the strip (1) to be exposed; B. connecting the inner end (1a) of the high-temperature superconducting strip (1) and the outer end (1b) of the high-temperature superconducting strip (1) to form a superconducting joint (2), and forming a closed blocky superconducting ring or superconducting cake. The superconducting magnet manufactured by the method is high in critical current density, and magnetic force lines concentrated in an area above a magnetic track can enter the superconducting magnet in a dense and concentrated way so as to be subjected to concentrated pinning, so that the superconducting magnet can produce strong suspension force and guide force.
